Wildfire Zone

The Wildfire Zone line generally follows what is called the "mountain front," which is a line connecting the average Eastern-most points on the 6400 foot contour line of the U.S.G.S. topographic maps. The State Forest Service concurs that this line indicates the predominant change from plain to mountain topography. The canyons are within the Wildfire Zone 1 because of the chimney-effect of the terrain. The location of the Wildfire Zone Line recognizes vegetation, slope, fire department accessibility, water supply, response time and infrastructure.

This line has been imposed on the Jefferson County Base Map to divide the County into two Wildfire Zones as described in Chapter 9 of the Jefferson County Supplement to the International Residential Code.

The guidelines shall be deemed to be the minimum inspection required and do not relieve the engineer or architect from any responsibility to conduct such additional inspections as may be necessary to determine that the foundation conforms to the plans and specification accepted for construction for the above referenced project. The inspecting engineer/ architect is required to consult the design engineer/architect on any unusual condition which may arise on the site. A set of foundation drawings bearing the Jefferson County Stamp must be on the job site. Any modifications to accepted plans must be approved by the design engineer and revised plans showing those modification submitted to the Department of Building Safety.

Verification of Inspection

Our representative has inspected the applicable portion of the foundation and subsurface drainage system (where applicable) in accordance with the guidelines set forth in this appendix chapter of the International Building / Residential Code. I do hereby verify that the portions inspected were in compliance with the plans and specifications on file with the Department of Building Safety. However, this verification is not a guarantee as to the overall performance of the foundation system.

Drilling logs for drilled pier foundations MUST be attached to the Foundation Compliance Form.
